Twitter CEO and cofounder Jack Dorsey gave an interview to The Today Show on Friday morning in which host Matt Lauer asked Dorsey about the problem of harassment on the site.

"It's disappointing, but reflective of the world," Dorsey said. "We see as much optimism as we see negativity."

He went on to explain that he sees Twitter as "empowering dialogue" so that people can talk about issues.

Lauer asked Dorsey whether he ever gets trolled on the site. "I get some complaints. I get some nastiness every now and then," Dorsey said.

Most people would just block someone if they're getting abuse online, but Dorsey hasn't done so. "I've never blocked anyone. I want to see what people are saying and I want to hear from them," he said.

Dorsey isn't the only famous person who has never blocked anyone on Twitter. Another high-profile user who has the same policy is President Obama. A 13-year-old child in the US claimed that he had been blocked by the President, a claim that was quickly denied by the White House.
